BREECH-LOADiNG FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 303,851, dated June 24, 1884.

Application filed January 16,1884.

' clear, and exact description of the invention,

such as will enable others skilled in the art to I which it appertains to make and use the same,

reference being had to the accompanying drawing,and to letters or figures of reference marked thereon, which form a part of this specification.

. My present invention relates to improvements in breech-loading fire-arms of the double-barrel type and it consists of a rod or connection, the forward end thereof adapted to extend through the frame and forward of the swivel, and engage with a camshaped openingin the fore-wood strap, the opposite end of said rod adapted to engage with thehammer, whereby the operation of opening the gun cooks the hammer thereof, all as will be more fully hereinafter set forth.

In the accompanying drawing is represented a longitudinal section through the front barrel and frame of a double gun, showing my improved device for cooking the hammer, the latter shown in position ready for firing, the gun shown being of the top snap-levcr pattern,the locking-bolt and its connections, however, not being shown, as they do not constitute any part of my present invention.

The following is a detailed description of said invention and the manner of operating the same.

A in the drawing represents the frame, provided with an opening, A, to receive the lockplate, &c., as common.

A represents an opening (under each barrel) in said frame and forward of thehammer, wherein is located the spring, &c., of said device, as fully shown.

0 represents a rod or connection, its forward end, 0, adapted to engage with the inclined or camshaped surface 0* of the fore-wood strap H, and forward of the swivel, as shown. The opposite end of the rod 0 is provided with a square coupling or head, 0, into which is (No model.)

screwed the rod C at C, the rear end, Z, thereof being adapted to engage with the hammer H for cooking the same.

(Z represents a spring which is adapted to keep the end 0 of said rod 0 in contact with the cam O. The sides of the square coupling G are fitted laterally inside the opening A, and serve to prevent the rod from turning.

The barrels I-P are adapted to be locked by a sliding bolt operated by the top snapdever,

R, as common to this class of fire-arms, said connections not being shown, as deemed unes sential to this specification. The firing-pin \V, hammer K, sears F F, and their connections are also as common, Therefore a description of these elements is considered unnecessary.

The following is the manner of operating the double gun herein shown, as provided with my invention. Assuming the hammer H to be in position against the firing-pin IV, after exploding the cap, (partly shown by broken lines,) the top lever, R, is pushed back toward the right, which movement withdraws the locking-bolt from the lugs of the barrel, and allows it (the barrel) to be opened. Now, while the barrel is being thus opened the camshaped surface C of the fore-wood strap H engages with the end G of the connection 0, and forces the rear end, Z, thereof against the front edge of the hammer H until full-cock is reached, the spring (Z in the meantime being compressed. In closing the barrel, the said spring (2 forces the connection 0 against the cam G until the barrel is fully closed, as shown, the end Z of the connection being correspondingly removed from contact with the hammer, thereby allowing the latter to be tripped, and completing the operation. By means of the threaded portion 0 of the rod C I am enabled to take up the wear of the parts as well as to accurately to adjust the same.

I am aware that it is not new, broadly, to lift the hammer by means of a rod and cam; butI do not know that device herein shown,the or its essential equivalent, has ever before been made or used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
